I know you probably don't want to hear this but you could consider a different set of cables. From what I hear Blue Jeans seem to be very high quality for the dollar. However I do recall reading about an HDMI cable that came with 90 degree bend connectors but I don't remember the brand. Also, I use monoprice.com HDMI cables for my setup and they work fine yet they are light weight so they bend and don't put much strain on the connectors. The monoprice cables are cheap enough to try and if you didn't like them you wouldn't be out much. If you want to try strain relief, you could hang them on onother cable, speaker wire bundle or power cord. If you don't like the idea of twist ties or other devices, they make a velcro strip tie that you can get a home depot and you get enough to organize your whole A/V rack for $5 or less. LOL
